Header Background Color

First you should create a “Child Theme” so that you are not making changes to the standard theme. If you don’t do this any changes you make will be reversed when the theme is updated.
Once you’ve done this add the following to the “style.css” file :

#header .c12 {
	background-color:#555555;
	}

substitute the color you want for the #555555 above
Hope this helps!

My pleasure Brian, great to know it worked for you!
